Uncle Norm - otherwise known as the "Norm the Normificent" - is trying to make a magic show appear! He's got the cape, the magic wand, and lots of hocus pocus, but seems baffled by how to do his own tricks. The show's chance of success improves when the Rads reveal a real "mathemagician", who explains the luck and logic behind simple magic tricks that use playing dice. Prepare to be astonished by the fact that opposite faces on a die always sum to 7! Presto math-amazing! This episode is about number cubes (die), their numerical configurations and their history in games and magic around the globe. In the curriculum, children are required to predict the frequency of an outcome in a simple probability experiment or game (e.g., "I predict that an even number will come up 5 times and an odd number will come up 5 times when I roll a number cube 10 times."), then perform the experiment, and compare the results with the predictions, using mathematical language. They are also introduced to number fact families (in this example different ways to sum to seven)
Time And Again
November 28, 2013
Alanna is overjoyed with the fact that she has won a prize in a school contest. It's a perpetual magnetic calendar. Kevin explains what a perpetual calendar is: it's a calendar you can use all year every year forever. Norm is impressed. "Wow! That looks completely calendar-iffic!. Let me stick it to my fridge". He grabs the box and trips, causing the pieces to fly wildly about (zing zang fwang!) and stick to metal surfaces all over the place. As they gather up the pieces of the calendar Uncle Norm expresses his interest in this magical calendar or Magi-calendar. He has lots of things to plan for, so exactly what does it do and how does it really work? Alanna visits a film director as they use calendars all the time to organize the shooting schedules for movies and TV shows. This episode is about the standard measure of time and the units of measure involved in measuring time. In the curriculum, children are required to solve problems involving the relationships between (minutes and hours, hours and days), days and weeks, and weeks and years (all as a unit), using a variety of tools (e.g.,calendars); identify and describe, through investigation, number patterns involving addition, subtraction, and multiplication, represented on a calendar; name the months of the year in order; and, read the date on a calendar.
Get In On The Fraction Action
November 21, 2013
Kevin and Alanna enter the clubhouse and find Norm on the telephone ordering his all time fave, a large cheese quesadilla! But could they slice it into four pieces instead of eight as he can't eat that many slices. Alanna is keen on helping Uncle Norm grasp the concept of fractions. She and her classmates have been asked to prepare different foods for school, foods from around the world, and she'll need to divide up her dish into equal portions. So while Kevin does some research she'll visit an expert to get some hands-on fraction action up close and relay the info to Uncle Norm, "This WE gotta see". In the curriculum, children are required to use concrete materials to represent fractions, divide whole objects into equal parts, and identify the parts using fractional names (e.g., one half; three thirds; two fourths or two quarters), and equivalent fractions--and to solve problems that arise from real-life situations. This episode is alsoabout the parts of fractions. The bottom part of a fraction is called the denominator: it "names", or indicates, the type of fraction that is described by the numerator (the top part). The denominator of a fraction tells you how many parts a whole is broken into. It can be a whole pineapple, a whole song, or a whole anything. If the denominator of a fraction is 4, then that indicates that the whole whatever is broken up into 4 equally-sized pieces. The word numerator comes from the Latin verb "enumerate", and counts the number of equally-sized pieces identified by the denominator that are contained in the fraction.
Bunnies' OK Corral
November 14, 2013
Uncle Norm's neighbor Mrs. Pearplum's prized bunnies have escaped! The Rads need to find a way to help her build a better bunny corral... but what shape should it be so they have the most space using just the amount of fencing she already has? The Rads visit a local hobby farm to learn how perimeter and area work together to create the best bunny corral, this side of the workshop! Perimeter and area are important real-world concepts in their own right, and their relationship certainly is no less important. This relationship can be intuitively challenging. For example, it is not uncommon for students and even adults to believe-at least at first thought-that a fixed perimeter, such as a given amount of concrete curbing, yields the same area no matter how you shape it into a closed figure. In this episode, the focus is on the relationship between perimeter (a one-dimensional measure of length) and area (a two-dimensional measure of space). The purpose of the episode is to illustrate that 2D shapes having the same area can have different perimeters by using the real world context of construction.
Tangled Up In String
November 7, 2013
Oops - he's on his way out the door and Uncle Norm finds a tear in his coat! Using duct tape (riiip!) to repair the tear won't work, so he burrows into a, Stuff 'n Such, junk pile, where he finds a sewing kit, but no thread! Rush, rush, he digs deeper and sees a piece of string art, made from lots of thread! Just as Uncle Norm is about to pull the artwork apart for his repair, Alanna and Kevin appear... in time to stop him from destroying an example of this colourful, and mathematical, art form. String art patterns are made with straight lines, but the finished product can give the illusion of curves. Uncle Norm and the Rads learn how to make their own rad-tastic string art! This episode is about geometric string art designs. Once a geometric design has been created, the points at which line segments meet can be given a numeric value. In the primary division, students use basic multiplication facts to create their geometric design. In addition, students must follow the directions (problem solving and pattern and sequence recognition) in order to successfully complete the project. In the curriculum, children are introduced to skip counting in grade one and by grade 3, they are introduced to multiplication math facts, and the definitions of factors and multiples.
Playing the Angles!
October 31, 2013
Alanna and Kevin arrive at the workshop and are puzzled to hear eerie music and the entire workshop decorated like a horror movie set. Uncle Norm is having a costume party for his 'hush hush' workmates. Kevin notices how the light hits the top of a lion statue and has an idea! Uncle Norm should put on a light show for his party. It's all about angles and light. And he knows just who to see to get some great tips. ,This YOU gotta see!, This episode is about standard measurement of angles using special instruments (the [simplified] protractor) and the size of angles, big, small, and right. In the curriculum, children are required to compare the size of angles in relation to the right angle (bigger than, smaller than) and to learn how "angle finders" (very simple protractors) can be used to measure angles.
Think of All the Probabilities!
October 24, 2013
Alanna and Kevin are looking out the workshop window watching the rain teem down. They turn to see a totally soaked and dripping Uncle Norm standing there. He takes off his sunglasses and wipes rain off his eyeballs - he is totally perplexed. After all, it was really sunny when he left earlier. Alanna talks to a TV weather forecaster about chances and probability. This episode is about predicting the frequency of an outcome by interpreting data provided on a scale from 0 (impossible) to 100 (certain). In the curriculum, children are asked to describe probability as a measure of the likelihood that an event will occur, using mathematical language (i.e., impossible, unlikely, less likely, equally likely, more likely, certain).
Uncle Norm's Roots
October 17, 2013
Uncle Norm finds Alanna and Kevin in the Workshop, squinting through a magnifying glass at small maple trees. He wants to know when they can get sap: bean seeds can grow as high as the tool shed in one summer, so why not a baby tree? The Rads explain that we measure a bean's growth in weeks and months, and Uncle Norm's growth in years and decades, but trees grow more slowly: over decades, centuries, and sometimes even millennia. They visit a sugar bush to find out more. A measurement always has units. For example, we measure time in millennia, centuries, decades, years, days, weeks, and hours. Without the unit, we do not know how much time has passed. The units that go with our measurements tell us what we are measuring and how much we have. In the curriculum, children are required to represent and explain, using concrete materials, the relationship among the numbers 1, 10, 100, and 1000, (e.g., use materials to represent the relationship between a decade and a century, or a century and a millennium).
The Kilo Conundrum
October 10, 2013
The Rads find Uncle Norm trying to figure out the weight and cost of healthy snacks by trying to weigh one grape. Kevin points out that one grape is really small, and doesn't weigh much at all, so it's really hard to check its weight on a bathroom scale. To satisfy Uncle Norm's kilo curiosity Alanna visits a veterinarian who will weigh some animals using different size scales. This episode is about accurate ways of weighing and appropriate use of the kilogram as a standard unit of measure. In the curriculum, children are required to choose benchmarks for a kilogram and estimate, measure, and record the mass of objects (e.g., can of apple juice, bag of oranges, bag of sand), using the standard unit of the kilogram or parts of a kilogram (e.g., half, quarter).
And Five Makes Ten!
October 3, 2013
At the last minute, Alannna's swim team needs someone to manage the cash box at a craft sale. It is up to Uncle Norm to save the day, in spite of his fear of change ... making change, that is. They learn more about "counting up" so they can provide customers with the correct change after Kevin talks to a bakery shop owner. This episode is about "counting up", an important computational strategy in the classroom which is the basis for "making change" in the real world. In the curriculum, children are required to represent and describe the relationships between coins and bills up to $10; estimate, count, and represent (using the $ symbol) the value of a collection of coins and bills with a maximum value of $10; count forward by 1's, 2's, 5's, 10's, 25's and 100's.
